Description
Technical Field
The present invention relates to the field of multimedia communication technologies, and in particular, to a method and a system for transmitting videoconference data, a computer device, and a computer program product.
Background
At present, in the field of video Conferencing, there are two modes, namely, an SFU (Selective Forwarding Unit) mode and an MCU (Multipoint conference Unit) mode, where each individual terminal transmits a video stream to a central server in the SFU mode, and the central server forwards the stream, and in this mode, the requirement on the load capacity of a terminal network is higher and higher as more and more terminals join in the SFU mode. Under the MCU mode, each terminal transmits the code stream to the server, the server performs mixed flow and transmits the mixed flow to each terminal, even if the added terminal only transmits one stream due to the server, the network load of the terminal and the processing capacity requirement of the terminal are greatly reduced.
Due to mixed flow in the MCU mode, the video of each participant is zoomed, and the definition of the picture when the video is transmitted to the terminal brings certain loss relative to the definition of a single-channel video in the SFU mode. The need to view the video of one participant more clearly and still hear the sound of the other participants in a particular scene becomes more urgent and practical.
In the related art, a server transmits a composite screen layout and information of each participant in the layout to a client for processing by the client. After the client obtains the original video address of a certain participant through calculation, a new playing connection is established to play the original code stream or the existing connection is closed to establish new playing. However, there are the following problems: each terminal needs to know the layout and other complex information of the playing picture; the server needs to notify frequently, and the terminal needs to change frequently; the same calculation content has redundancy and the calculation capacities of different terminals are different too much; a connection or a playing window needs to be established, so that terminal resources are wasted; the delay or pause of the playing due to the newly established connection and the playing window is poor in user experience.
